Glad to see it went well. My first hang was in 16 degree weather, no wind with an ENO double and ENO profly...figured I was only a quick 1 mile hike from the car if things didn't go right. My bag had a zipper failure when I went to use it, so I spent the night stupidly gripping it closed instead of wrapping up in it like a quilt. nonetheless, I slept ok. Put hand warmers in my wool socks to ward off frostbite and was just as comfortable, if not more so than my ground dwelling friends. If you hang much, you'll be upgrading your fly I suspect.
